community pride and provide educational material for young Aboriginal people,. This could
also provide an opportunity to help foster a better understanding
and appreciation as
Aboriginal culture among the wider Australian society.

Perhaps the most beguiling application of astronomical observation is associated with
the behavior of one Australia’s most iconic birds , the emu. `The Emu in the Sky`, as it is
called, describes a carving that is clearly visible on a rock located in Ku-ring-gai Chase
National Park, north of Sydney. It depicts an emu is somewhat unnatural position for a real
emu , with the legs folded behind it. That is, until it is observed that there is a huge and dark
shape in one of the `dark` areas of the Milky Way that resembles an emu. This `emu` swings
around the sky each night, its starting point at dusk changing as the year goes by and the
season change. In April the body of the `Emu in the Sky` reaches a certain angle, and people
know it is the season to go and find fresh emu eggs, a rich highly valued food source. When
the angle of the representation of the emu on the rock face matches the `Emu in the Sky`,
the harvest might begin. The folded legs signify that the emu is sitting on the nest.
The Emu in the sky exemplifies one of the key principles of Aboriginal cultures: what is in the
sky is of what is on Earth . Aboriginal people also apply this concept to construct annual
calendars . Often based on six reasons ,Aboriginal calendars are relatively complex and are
generally constructed from the heliacal rising of stars (i.e when the star first becomes visible
above eastern horizon for a brief moment just before sunrise)

Dr Philip Clarke of federation University Australia has documented how tha Kaurna
Aboriginal people of South Australia use the rising of they call Parna ,one of the brightest
stars in the night sky .Its appearance just before sunrise indicates that the hot ,dry summer
is ending and the autumn rains will soon arrive .The lands of Kaurna include the ADELAIDE
Plains ,which are prone to flooding .Therefore ,knowledge of when the arrival of autumn is
imminent allows them time to build their large, waterproof huts ,which are known as wurlies.
Not only were the positions and movements of individual stars
used to predict seasonal
changes, the scintillation of stars also informs Aboriginal astronomers of a change in the
weather or season. ”They can tell by the degree of how much the star twinkles or changes
colour to gauge the amount of moisture in the atmosphere”, explains Hamacher. “They then
know wheter a storm is approaching or the wet season is coming”.

It is clear that aboriginal cultures contain a wealth of astronomical knowledge. This
knowledge incorporates a deep and sophisticated understanding celestial and terrestrial
events and should be viewed through the prism of an interconnected world-view:
a paradigm
in which the Aboriginal people saw themselves not a separate external observers, but
integral component of nature and the universe.
